This is pruely hypocritical but if you burned 3500 calories a day would you weigh a pound less the next day? Again, pruely hypothetical and the only way I know you could burn that much is by going on a thru-hike lol.

    No, because the body doesn't gain/lose on a 24-hour cycle. It's a continuum.

    I would eat a whole jar of crunchy peanut butter.... to keep the space time thingy from destroying the world.

    If you managed to burn 3500 net calories in a 24 hour period you'd probably lose a lot more than a pound of scale weight as you'd burn through all your glycogen with the associated water weight attached to it. You'd almost certainly not lose a pound of fat though, as with that extreme a deficit you'll end up catabolizing a reasonable amount of lean body mass as well.

    Either way, a terrible idea.

    The scale might actually show a weight gain due to your body retaining fluids to repair itself.

    It would eventually show up on the scale...if you don't eat 3500 extra calories the next day!

    On the hiking...yes it burns a lot of calories but for me at least...I am always extremely hungry afterwards!

    If you created a deficit of 3500 calories per day, you may not weigh 1 lb less the next. In fact in many of our experiences you may weight 1 lb more. But if you give it say four weeks, your average rate of loss if 3500 is truly your deficit would indeed be a pound per day.

    Deficit being calories eaten, minus (calories burned just existing and getting through a normal day, plus calories burned through intentional exercise)

    This is really interesting thanks for answering my question! Just so everyone know I dont plan on trying this it was a thought that came up during an 8 mile walk where I almost unintentionally burned that amount.

    actually you probably would weigh less the next day but that doesnt mean that it's from fat loss. could be a lot of water.

    and great job on walking 8 miles OP

    ^This. Also, I hope you compensate with a lot of food for all that burn!

    I do it occasionally, but I would never leave my deficit at -3500 for the day, so after I've had my pork out session on returning, the next day I would never show a pound loss, but I will be able to eat over 5000-6000 cals those days and still lose weight ;)

    As a road cyclist that does distance rides, I have (at least according to MFP calculations) burned 3500 in a day.
    And no you don't lost a pound over night. In fact, burning excessive calories during cycling or hiking as you mentioned is a fine balance or calorie and water intake. I have found that my body actually holds on to weight if i don't eat enough of the calories I burned back. But that is just me and my strange body that doesn't want to let the fat go :)

    If you do decide to an activity that will burn that much make sure to plan ahead, know what to eat before, during and after. Bonking is quite common with excessive exercise and believe me there is nothing worse than being 2hours from home on a bike and not having one ounce of energy left but knowing you have no other choice but to ride :P

    You'd be loosing a lot of muscle. It won't kill you, I burn around 2900 calories on an active day. So if you want to try go ahead the human body is amazing at healing itself. Just drink a **** ton of water and sleep more if you even try to attempt too.
    Remember that girl from the biggest loser, rachel?
    She lost a lot of muscle and fat.

    I would go eat....3000 calories!!! Your body needs fuel.....ESPECIALLY if you burned that much. And like all the people on here said, if you don't give your body the necessary fuel to rebuild/restore you will slowly turn into nothing!

    i would wonder what went wrong for me to have had such a sedentary day. but hey, everybody needs a rest day now and again, right?

    I doubt you almost burned 3500 calories on an eight mile walk. If you go such a high amount from MFP or from an IPhone pedometer, it's a guaranteed overestimation.

    IDK about 3500 cal (like a pp said, if I burned that much in one day, you'd probably way MORE the next day from SWELLING, lol)...


    But I *do* remember one day where I burned 2000+ calories snowboarding. I was stoked, until I realized that I'd eaten 1800 calories of trail mix alone that day!!

    Not completely clear on what the question is. If you're talking about 3500 calories a day of exercise burn, that's pretty doable for someone in good shape. How much you'll lose after that depends on how many of those calories you eat back.

    If you're talking about having a 3500 calorie deficit for the day, that's not a good idea unless you're very obese, because the body can't metabolize fat stores quickly enough to fuel that. Meaning you're going to be burning up parts of your body you'd rather not burn up.

    Well, I am 100 pounds overweight right now and it took me four hours.

    Before I got sick and gained all this weight I got lost one time on the bike path in Monterey CA and ended up biking twenty miles round trip. Half way through I had to stop and ended up napping on the beach. After that I started biking 10- 30 miles a day and eating a ton while still losing weight. :)

    I'm planning a 50 mile ride today. I'm also planning eating most of what I burn back, but I'm guessing I won't eat enough to make up for the whole deficit. I'll let you know what the scale looks like tomorrow.

    Well, I am 100 pounds overweight right now and it took me four hours.

    I plugged in some numbers to greatly over estimate your weight and effort and it still came up to half that. I stumbled across this formula for net calories burned:

    Jogging/running: 0.63 X body weight (lbs) X distance (miles)

    Walking replace .63 with .3.

    I know it was just a quick point of curiousity for you, but this a valuable lesson. People often wonder why they're not losing weight or not losing as quickly as they think they should. It 100% either has to do with under estimating food eaten, or over estimating calories burned :)

    8 miles walking @ 300 pounds -> about 800 calories.

    How long did it take you?

    If I use the METs value for walking 2.8-3.2mph and apply it to a BMR of 1843 (Katch-Mcardle for 300lbs. and 50%BF), I estimate walking 8 mph burns around 1400 gross or 1000 net calories. Meaning 400 of the 1400 you would've burned sitting at home those hours.

    https://sites.google.com/site/compendiumofphysicalactivities/Activity-Categories/walking

    So, yeah, 3500 is not even in the ballpark.

    Where did that even come from? If I put in walking 3mph for 160mins. (comes out to 8 miles at moderate pace) in MFP for me it spits out around 600 calories.

    I can honestly say in my experience as I have done this multiple times, yes even in my diary, I am extreme with the diet and exercise, a person DOES NOT LOSE A POUND OVERNIGHT from that much exercise. You could do 5,000 even 10,000 if you survive, you won't lose weight. I have sometimes weighed more after.

    However you lose weight the next few days, half a week, and it starts to come off like crazy.

    If you want to believe it eats your muscle, fine but gains doesn't explain that. If I can lift better one day versus another, go longer, am I supposed to believe my muscle that I built up for years is disappearing daily? No, I don't.

    Show me pictures of other people, sure... but they aren't me. I used to be thin from my first weight loss journey long ago and I didn't lose muscle back then either. Call it denial if you want.

    But for the OP, starting out in weight loss, this should be totally avoided. You have to be extremely fit, and mentally fit to even attempt the real number plus not binge eat after.

    I have the same experience. I think the calories MFP gives me for biking are way too much. I bike practically every day and I think my body is so used to it, that I do not burn so many calories. I also seem to be gaining sometimes instead of losing despite biking three or four hours a day. The irony is the more I bike the less hungry I am and I probably do not eat enough. But in the long run I always drop weight if I bike every day.

    Well, I could certainly be wrong then. :smile: But, it still seems overestimated.
